Mobile enterprise applications typically access data from the enterprise’s various applications to support collaborative working processes. Allowing the mobile application to access these data online only would be a major hindrance for mobile workers that cannot assume a constantly available network connection. This problem can be handled by middleware systems, which provide a way to prefetch data on the mobile device. But changes and events on the central data cannot be foreseen; moreover, they cannot be delivered to disconnected mobile clients. We introduce a distributed event service named SelectiveDES for managing and delivering events to mobile clients in unpredictable network environments. SelectiveDES is designed as an addon to common invocation-based middleware systems; it is based on the publish-subscribe paradigm and supports selective multi-channel communication and notification delivery.
